Ce travail vise à étudier l'impact de différents types de travaux de la végétation et du sol ainsi que le rôle des rémanents sur la régénération du pin d'Alep. Après une coupe de régénération dans une pinède âgée, les travaux suivants ont été testés : broyage mécanique de la végétation, broyage suivi d'un crochetage simple ou double, brûlage contrô...

The effects of ambient and elevated ozone (O3) levels on photosynthesis, growth, pigment, biomass and element contents of Aleppo pine (Pinus halepensis Mill.) were studied for two growing seasons (1997, 1998). Two-year-old seedlings were exposed to elevated O3 in open-top chambers. The treatments were charcoal-filtered air and non-filtered air + 50...

Two-year-old Aleppo pine (Pinus halepensis Mill.) seedlings were exposed to ambient air+50 ppb O3 in open-top chambers (24 hours/day, 7 days/week) during May-October 1997 and to ambient air+70 ppb O3 from May 1998 onwards. One growing season fumigation with ozone did not affect the pigment concentrations of the current-year (c) needles, nor were th...
